3D Systems reports that it has launched a new material, Cibcitool SL7540, designed to create parts that mimic end-use plastics in stereolithography (SLA) applications, ranging from snap-fit testing to the creation of multi-component assemblies. Considered to be a cost-effective resin, it can be used with 3D Systems' SLA 3500, 5000 and 7000 systems and reportedly enables users to move quickly from three-dimensional designs to high quality, functional finished parts.
Developed jointly with Cibia Speciality Chemicals under a partnership agreement, SL7540 is said to have been formulated to provide durability and accuracy, even when worked at the high speeds of 3D Systems SLA 3500, 5000 and 7000 systems. The resulting resin is claimed to exhibit mechanical properties similar to those offered by popular thermoplastics, such as polypropylene, polystyrene or polyethylene.
For example, parts created using the resin are reported to have the flexibility to withstand the rigours of functional testing and, in the majority of cases, the need for interim steps such as bridge tooling can be eliminated when using 5L7540. In addition, the resilience claimed of the material means that models could be drilled, threaded, machined and polished, allowing users to test and demonstrate fully-functioning point.
The durability of SL7540 is also believed to make it suitable for mould making applications. Master patterns built using the new resin are reported to be capable of producing multiple moulds, even for demanding projects involving complex patterns, thin part walls, or elevated process temperature. Consequently, prototypes can reportedly be tested rigorously while maintaining the integrity of the part geometry.
